6R-0WL first appeared as a purchasable companion for players in the MMORPGStar Wars: Clone Wars Adventures released by Sony Online Entertainment in 2010. The droid could be bought only during the Life Day event for 300 station cash, a premium in-game currency players have to buy with real money. Given that 6R-0WL's purchase is entirely optional, this article makes no assumptions about if it was bought. The droid's name spells out the word "Growl".
